The equity multiplier is a financial leverage ratio that measures the amount of a firmâs assets that are financed by its shareholders by comparing total assets with total shareholderâs equity.

The method of Lagrange multipliers is a method for finding extrema of a function of several variables restricted to a given subset.Let us begin with an example.n this section we apply the method of Lagrange multipliers instead. The key to understanding this technique is the following figure, which plots the constraint function and the level curves of f(x,y).
